From Tokyopop: Gun has always been a problem kid, but after a tearful plea from his mom, he decides to turn over a new leaf. Vowing to abandon fighting and troublemaking, Gun transfers to a new high school, attempts to be a good student, and rents a room at the local coed dorm. There he falls for Seung-Ah, the dorm owner's granddaughter. However love is not to be for this couple, as sexy Ji-Ae's untimely advances always thwart his attempts to woo the innocent Seung-Ah.

He resides in the city of Fayon, inhabited by a long lineage of warriors. The newest leader in line to claim the head position of the village is a young woman by the name of Iris Irine, who trains with her close friend Chaos to become a suitable leader for her people. Meanwhile, Fenris Fenrir searches for Balder's reincarnation to bring about Ragnarok.
